Sequential Thinking MCP Server

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.

Features

Break down complex problems into manageable steps
Revise and refine thoughts as understanding deepens
Branch into alternative paths of reasoning
Adjust the total number of thoughts dynamically
Generate and verify solution hypotheses

Tool

sequential_thinking

Facilitates a detailed, step-by-step thinking process for problem-solving and analysis.

Inputs:

thought (string): The current thinking step
nextThoughtNeeded (boolean): Whether another thought step is needed
thoughtNumber (integer): Current thought number
totalThoughts (integer): Estimated total thoughts needed
isRevision (boolean, optional): Whether this revises previous thinking
revisesThought (integer, optional): Which thought is being reconsidered
branchFromThought (integer, optional): Branching point thought number
branchId (string, optional): Branch identifier
needsMoreThoughts (boolean, optional): If more thoughts are needed

Usage

The Sequential Thinking tool is designed for:

Breaking down complex problems into steps
Planning and design with room for revision
Analysis that might need course correction
Problems where the full scope might not be clear initially
Tasks that need to maintain context over multiple steps
Situations where irrelevant information needs to be filtered out

Configuration

Usage with Claude Desktop

Add this to your claude_desktop_config.json:

npx

{
  "mcpServers": {
    "sequential-thinking": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    }
  }
}

docker

{
  "mcpServers": {
    "sequentialthinking": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "mcp/sequentialthinking"
      ]
    }
  }
}
